To verify IFS (In Field Scan [1]) driver functionality, add the following 6 test cases:
- Verify that IFS sysfs entries are created after loading the IFS module
- Check if loading an invalid IFS test image fails and loading a valid one succeeds
- Perform IFS scan test on each CPU using all the available image files
- Perform IFS scan with first test image file on a random CPU for 3 rounds
- Perform IFS ARRAY BIST(Board Integrated System Test) test on each CPU
- Perform IFS ARRAY BIST test on a random CPU for 3 rounds
These are not exhaustive, but some minimal test runs to check various parts of the driver. Some negative tests are also included.

Changes: v1 to v2:
- Rebase to v6.10 cycle kernel and resolve some code conflicts
- Improved checking of IFS ARRAY_BIST support by leveraging sysfs entry methods (suggested by Ashok)
A gentle ping on this patch :)
Best Regards, Thanks!
